ALONZO F. HAVENS, OF BROOKLYN, NEW YORK.

IMPROVEMENT lN ELEVATED TRACKS OF WIRE OR ROPE.

Specification forming part of Letters Patent No. 123,993, dated February27, 1872.

To all whom it may concern:

Be it known that I, ALONZO F. HAVENS, of Brooklyn, in the county ofKings and State of New York, have invented an Improved Elevated Track ofWire or other Hope; and the following-is declared to be a correctdescription of the same.

This invention is for supporting and holding the rope in such a mannerthat the carriage with Wheels may run thereon with facility and meetWith little or no obstruction, and that the said track may pass aroundcurves for changing the direction thereof.

I make use of a shield or support to clamp and hold the said, rope; and,Where the direc-v tion of the track is changed, this shield is ofsufficient length and forms an arc of a circle, the rope passing throughthe same, and hence capable of being strained up with the requiredtension to support any load hung from the carriage that runs on thesame.

In the drawing, Figure l is a plan of the said track at one of the bendsin the same,

and Fig. 2 is a cross-section of the shield and rope.

The rope or is to be of wire or other suitable material, and of a lengthto reach the extent of the elevated track, and the ends are attached tosuitable tighteners or shackles that are supported by beams or posts b.A bar or rod might take the place of the wire rod. The shield c is madein an inverted U-form, with the opening of the width of the rope, andthis is placed over the rope, which is supported in a semicirculargroove in the top of the bearing-bar e, and the shield 0 is clamped uponthe rope by the insertion of Wedges or keys f, that draw the partstogether. The top part of the shield cis made very thin, so as not tointerfere with the rollers g of the suspending-carriage h, runningfreely from the rope upon the shield and off the same. The shield andsupport are to be supported by posts or suspended by hangers k, at oneside, and placed at suitable distances apart; and where the trackchanges its direction, the shield is to be made as an arc of a circle,through which the rope passes. In order to give direction to thecarriage h, a curved fender, Z,- is placed above and at a littledistance outside the curve, to turn the carriage into the line of thecurve and prevent the wheels running off.

I claim as my invention- 1. The shield c and bearing-bar c, to clamp andsupport the rope of the elevated track, substantially as set forth.

2. The fender Z, in combination with the rope-track a, supporting-bar e,and shield c, as and for the purposes set forth.

Signed by me this 29th day of September, A. D. 1871. i
